ABSTRACT:
The angular movement of a knee joint of the kind comprising a four bar linkage is controlled by the frictional engagement of a shaft, pivoted at one end to one of the links, with a pivotable plastics bush located between the ends of another link. The plastics bush may be tightened around the shaft to adjust the frictional restraint on the movement of the joint.
